This movie shows the life of teenagers on the last day of school in 1976. Its all about partying and having fun. So if you didn't do any of this stuff in high school you won't relate to it, I'd say thats the problem for most of the people that gave it a bad rating. Even my parents enjoyed this movie. Especially since they graduated right around that year and I would imagine have experienced the pothead, keg parties first hand. I've seen it 100 times and will probably see it a 100 more times in the future.
